low electrical power '00 bravada
replaced heater core and reinstalled the dash now i cant start engine or use anything electrical. i can hear a buzz from a relay and dome light comes on very dim while buzzing intermitently. checked all connections in dash nothing loose or unplugged. relay is located on top of a ''power block'' behind dash on driver side, removed 1 relay and it no longer makes a buzz. tried to switch with another but same result. OMRON 12088567 $20 ea. could this be the problem?someone said bad ground but where is the wiring harness grounded. checked all grounds underhood.

Re: low electrical power '00 bravada
Did you disconnect the battery negative before you started. If you didn't I would check for a blown fuse.

Re: low electrical power '00 bravada
If fuses are good check the grounds on left and right side of dash.
Let us know how it goes.
